Definitions

  • the invention relates to a device for fastening components of Alarm systems according to the preamble of claim 1, such as. B. from the Document US-A-4 631 526 is known.
  • Alarm systems contain components for monitoring individual areas, For example, sensors on access doors, windows, etc., by the Alarm center are set down. These sensors are usually in housings arranged and attached to appropriate places, mostly walls.
  • the Fastening takes place in known components so that the Fasteners, such as screws, when fully assembled Component are not accessible. For this purpose it is necessary that Open the housing during assembly and the assembled, closed Secure the housing against opening.
  • the invention has for its object arranged in a housing Design components of alarm systems so that the attachment can be done quickly and without opening the housing, taking the components are protected against sabotage.
  • the rear wall of the housing has a cutout a fastener, such as a screw can be performed.
  • a fastener such as a screw
  • Within the housing is an arrangement for monitoring the position of the Fastening means arranged, in particular a change in position of the Fasteners within the housing detects and an alarm signal delivers, which is preferably forwarded to the alarm center.
  • the device according to the invention enables simple attachment of Components of an alarm system possible by the housing using the Recess in the fastener can be hooked.
  • Fasteners can be used using screws or hooks are anchored in a wall, for example.
  • the fastener is there not accessible because, for example, the screw head or the hook in the Protrude inside the housing.
  • the arrangement exists to monitor the position of the fastener from a switch that is actuated through the recess when the fastener is carried out. In this way, the position, in particular the presence of the fastener in the housing supervised. Once the fastener is removed from the housing, i.e. when the housing is removed from the mounting location, the switch is back on opened or it changes its state, which triggers the alarm. False alarms can be avoided by switching the switch arranged or executed so that a slight movement does not lead to a Switch actuation leads.
  • Another advantageous embodiment of the invention provides that the Arrangement for monitoring the position of the fastener indirectly or is arranged directly on the inside of the housing front wall. at Opening the case changes the relative position of the Position monitoring arrangement for the fastener and it becomes a Opening the housing is recognized and leads to an alarm.
  • the housing in such a way that it can only be opened when not attached. This can For example, be achieved by the screws that hold the housing parts hold together, only accessible from the rear wall of the housing.
  • the housing in which a component of an alarm system, for example a sensor for room monitoring, which is not shown in the figure, is arranged, consists of a housing rear wall 2 and a housing front wall 3, which are connected by means of a screw 4.
  • the rear wall 2 of the housing has a recess 21, 22 through which a fastening means 8, in the present case a screw, can be passed.
  • the recess 21, 22 has a lower part 22, the diameter of which is larger than the head of the screw 8 to be passed, and an upper part 21, the diameter of which is smaller than the screw head and larger than the diameter of the shaft the screw 8 is.
  • the screw 8 is screwed, for example, into a wall 1, the screw head being at a distance from the wall 1.
  • the housing 2, 3 is fastened to the screw by passing the lower part 22 of the recess over the head of the screw 8 and then lowering the housing so that the shaft of the screw 8 lies in the region of the upper part 21 of the recess.
  • a switch 6 with a switching tongue 61 is arranged inside the housing. The switch is arranged within the housing so that the head of the screw actuates the switch tongue 61 when the housing is attached. If the housing is removed by an unauthorized person, an alarm signal is issued. A corresponding signal is preferably sent to the alarm center. If the housing is removed by the user, an alarm can be suppressed by disarming the alarm system entirely or only regarding the component.
  • the switch 6, 61 can either be directly on the front wall of the housing be attached or, if the dimensions of the housing are not allow, by means of an insert 7 and a fastener 5 with the Be front wall connected.
